Topic: Do you classify part or all of the image? (Read 16595 times)

I was whizzing through galaxies when up came what looked exactly like a star, but without the usual 4 "spikes". So I classified it as a star or artifact.

When I could go into the image and zoome out, I quickly realised that this was not a star but the centre of a nearby elliptical galaxy. How do I go back to the thing and put a correct and meaningful classification in place of the nonsense I have written? How do I zoom in and out *before* classifying?

Regards

Welcome to the Zoo !To "go back" I think you have only to click on the icon, in the lower row, you've just choosed. The choice is proposed again. But corrections are possible only while classifying, not after...To zoom in and out before classifying, I think it's no possible...

Hi Davidin GZ1 you could zoom in/out before classifying. In GZ2 this is not possible.And I'm afraid you can't go back and redo a classification.But don't worry, lots and lots of people will get the same galaxy to classify.Welcome to the Zoo and happy hunting

Welcome to the zoo David! And don't worry, because if something doesn't match up with what people are saying about it, the zookeepers can use their own checks to find out why.

Very early on, nearly 2 years ago I should think, zookeeperKate did an Object of the Day of 3 beautiful, close-up galaxies which had mostly been classified as stars - because they needed zooming out on.

What your classification tells them is to adjust the image to zoom it out more for future classifiers, if that is possible.

You can change your mind during the classification process but not afterwards, sorry. Even so, don't worry if you have made a mistake, we all do now and then.

I just got this one: I marked it Smooth, In Between, Yes, Other, based on the large galaxy at the middle bottom, even though there was nothing at the "center." Was this correct to do, or should I have clicked Star/Artifact instead?

Hi AbuMaiayou should always classify what's in the centre of the image, so in this case star/artefact would've been correct. Could you please post the ref.number in future posts, that makes it easier to check things.Welcome to the Zoo and have fun !

I have a dilema. I classifid this as haveing lumps (4+, clump Ect ) and I then intended to state about the spiral, but found I could not. So in this situation what is more importent. Classafing the Galaxy or whats in it.AHZ10002dx
